Re-index all internal functions to make room for imported external functions
...
Linked external functions must be declared in the Import section,
and they must come first in the function index space.
In other words, internal function numbers start at the number of imports.
However we don't know in advance how many builtins the code may call,
and we don't want to add more passes over the full IR. Instead we re-index
function references at the end of code generation.

Add linker data for strings, and deduplicate them
...
For references to addresses of constant strings, we make an entry in
reloc.CODE and configure the relocation type to say it points at a
memory address. (At least I think this is right, I can't test it yet!)
The same info can also be used for de-duplication.
It turns out we don't need reloc.DATA. I had misunderstood it.
The use case for that would be constant nested data structures,
where constant data would contain pointers to other constant data.
I don't think we're doing this in Roc at all, but not sure.

Temporary setup to gradually migrate sections from parity_wasm to our own module_builder
...

Now we also have export section, and a way of switching them over one by one,
running tests in between.

Change custom section names to string slice

We will never need to create these names dynamically.
e.g. "reloc.CODE", "reloc.DATA", and "linking" will all
come from specific places in our backend code.
It's a different story for function names etc.

Refactor the optimisation for immediately-returned Let statements
...
The original intention was to avoid creating a local when we define
and immediately return a primitive value. But now our default path
does avoids unnecessary locals anyway!
For StackMemory values we do need an optimised path but it's nicer
to just pass a flag to Storage::allocate.
